SPECIFICATION forming part of Letters Patent No. 741,386, dated October1 3, 1903.

Application filed March 9, 1903. Serial No. 146,827. (No model.)

T0 at whom it may concern:

Be it known that I, JosEPH TETLOW, a citizen of the United States,residing at Biddeford, in the county of York and State of Maine, haveinvented certain new and useful Improvements in Separators; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to improvements in separators for use in connectionwith ringspinning frames, the object of which is to prevent the threadsfrom becoming tangled as they balloon out in the operation of spinning.

In ring-spinning the ring-rail reciprocates vertically relative to thebobbin. When the rail is at or near its highest point, the length ofyarn from the guide-eye to the rail is short, and therefore has littletendency to balloon. It has been customary to prevent tangling of thethreads by the interposition of separator-blades between the bobbins andto move said blades up and down by the ring-rail. Sometimes the bladeshave been moved vertically by the rail, and sometimes the blades havebeen pivotally mounted and are turned upwardly and backwardly by theupward movement of the rail. I therefore do not claim, broadly, the useof movable separatorblades between the bobbins. Y

The object of v the present invention is to so construct and arrange theseparator-blades that they may be turned entirely out of the path of thering-rail during the upward traverse of the rail and when the tendencyto balloon is inconsiderable and returned into position between thebobbins automatically and quickly when the ring-rail descends to a pointwhere the threads are in danger of tangling. In order to do this, it isnecessary that the blades be of considerable vertical extent, andbecause of the limited amount of vertical movement possible for theblades it is necessary that the blades be of peculiar construction, bothas to their shape and as to the position which they occupy relative tothe ring-rail.

The object of my invention is, further, to provide means forautomatically regulating the movement of the separator-blades both intheir upward and downward movement to show the attachment of myimprovements thereto, including the ring-rail, parts being broken away,the separator blades being shown in operative position. Fig. 2 is asimilar view showing separator-blades out of op= erative position, Fig.3 is a side elevation and front view, respectively, of the finger on theseparator-carrying frame, by which the separators are held in operativeposition for a time after the center of gravity of the frame changes andby which they are returned from inoperative to operative position. Fig.4 is a side elevation of the intermediate separator-frame support andits hanger, and Fig. 5 is a side elevation showing a difierent form ofthe same.

Same letters of reference refer to like parts.

A represents a roller-beam of a spinningmachine. Secured to said beam isa suitable bracket, consisting of a base B, adapted to be secured to thefront of said beam, verticallypositioned bars 0, having vertical slots Din their lower extremities, and horizontal bars E, having longitudinalslots F therein, said latter bars being thus horizontally and verticallyadjustable relative to bars 0 by means of bolts G and set-nuts H. Theseparatorcarrying frame I has journal-bearings J at the endsprojectinginto vertical slots Kin said bars E, and lugs M, adapted topivot and slide upon bearing L on said bars. The journal-bearings J andlugs M are positioned relative to each other and to said slots andbearings L so that when the frame, with the attachments hereinafter tobe described, is in operative position the center of gravity is suchthat the frame will normally remain in said position and when tippedbeyond a certain point, as by the upward movement of the ring-rail, thejournals descend in the slots and draw said lugs back on the bearingsuntil the center of gravity shifts to the other side and the frame tipsback until its further backward movement is opposed, as by a stud N,impinging the under part of bearing L or in any other convenient manner.Secured to the separator-frame in any convenient manner are a series ofseparatorblades P, adapted to project between the bobbinswhen inoperative position and to be tipped back out of the way of ring-rail andbobbins when not required.

To fully safeguard the yarn, it is necessary that the separator-bladesbe of considerable vertical extent, and to enable the blades to beturned back underneath the roller-beam and out of the way both of thering-rail and the bobbins it is necessary that a considerable portion ofthe blades extend below the point of attachment to the carrying-frame.The frame to which the blades are attached and which is pivotallymounted in a bracket, as before described, must necessarily bepositioned close to the path of the ring-rail, so that in order for theblades to remain in position until the rail has ascended to a pointwhere the ballooning renders tangling of the threads impossible thelower extremities of the blades are curved and the rear and under sidescut away, as seen at P, and the position of the blades relative to thering-rail is such that when the blades are turned upwardly to horizontalposition the rail engages the blades at a point close to where they areattached to the carrying-frame, or near the point P. It will be evidentthat because .of the peculiar construction of the blades and theposition of the carrying-frame relative to the path of the ring-rail theblades can remain longer between the bobbins than would otherwise be thecase and yet permit the blades finally to pass out from between thebobbins and under the rollerbeam. Inasmuch as the blades are mounted ona pivoted frame, they would tend to remain either in operative orinoperative position under the influence of gravity. We have seen thatthey are moved upwardly and backwardly by the ring-rail in its ascent.To prevent the blades from tipping back as soon as the center of gravitychanges, which would be before the danger of tangling had ceased, Iattach to the under side of the ring-rail a leaf-spring R, which may becurved downwardly and then turned upwardly in front of the edge of thering-rail, as seen at R, the end of the spring being free. This springis positioned so as to be engaged by a projecting finger Q, secured tothe blade-carrying frame substantially at right angles to the blades,whereby the tipping back of the blades is further retarded. At theproper time the finger Q passes out of contact with the spring and theblades tip back on their frame beneath the roller-beam until the lug Nengages the under side of the bearing L which limits the backwardmovement. 7

Con-

versely, as the ring-rail descends the spring engages the end of thefinger Q and turns the blades once more down upon the rail between thebobbins. It is sometimes desirable when the blades are tipped back underthe roller-beam to have the path of the ringrail unobstructed. For thispurpose I pivot the finger Q to the blade-carrying frame, as seen at Q,Fig. 3, and provide means for locking the finger in operative positionand for unlocking it, so that it can be made to assume a positionsubstantially parallel to the blades, and thus when the blades aretipped out of the path of the ring-rail the finger will not be therebyprojected into the path of the rail. in any convenient manner, as by alug Q engaging an offset Q The finger may be held yieldingly locked, ifdesired, by means of a spring Q mounted on the pivot, so that the fingermay be moved against the spring until it clears the offset.

In consequence of the length of the bladecarrying frame and the weightthat it supports it becomes necessary to provide an intermediate supportbetween the ends, and inasmuch as the frame has a vertical as well as abackward-and-forward sliding movement it is necessary in order that theframe may be constantly supported to provide a pcculiarly-shapedsupport. This Ihave shown in Figs. 4 and 5. My intermediate framesupportS is attached to the roller-beam or the base of the bracket in anyconvenient manner and is provided with a bearing-sun face S, extendingdownwardly and rearwardly. Thus when the blade-carrying frame tips backthe top rests upon the bottom of the lower part of the bearing-surfaceS, as seen in Fig. 2. As has been before stated, it is important thatthe ring-rail may travel as near the blade-carrying frame as possible,and in order that the frame-support may not extend into the path of thering-rail I form the support in the manner shown in Fig. 5, in which aportion of the bearing-surface is on a swinging section S so that as therail ascends it tips the blade-carrying frame backward and downward,releasing the pivoted section, which then tips toward the rollerbeam,the lower part of the pivot-section being heavier than the upper part.This takes place at the time that the ring-rail is adjacent the support.When the blades tip back into position as the raildescends, the bearingof the frame returns to the outer end of the support, moving the pivotedsection into the position shown in Fig. 5. Further movement is preventedby a stop S Having thus described my invention and its use, I claim-- 1.The combination with a separator-frame having a series ofseparator-blades secured thereto, said blades having a considerableextension above and below the point of attachment, said frame beingpivotally mounted in suitable brackets, the contour of the lower Thefinger may be locked mounted on suitable supports and having a' fingersecured thereto at substantially right angles to the blades, of aring-rail provided with a spring attached to the under sidethereof,-said rail being positioned so as to actuate the blades upwardlyby direct engagement therewith as it ascends and downwardly by theengagement of said finger with said spring.

3. The combination with a separator-frame provided with a series ofseparator-blades, said frame being pivotally and slidably mounted onsuitable supports and having a finger secured thereto at substantiallyright angles to the blades, of a ring-rail provided with a springattached to the under side thereof, said rail being positioned so as toactuate the blade upwardly by direct engagement therewith as it ascendsand downwardly by said finger extending into the path of the springattached to said rail and means for disengaging said finger so as torender it inoperative. S

4. The combination with a separator-frame pivotally mounted in suitablebrackets and adapted to have a rotary and sliding movement, of anintermediate frame-support having a supporting surface extendingrearwardly and downwardly.

5. The combination with a blade-carrying frame pivotally mounted insuitable brackets and adapted to have a rotary and sliding movement, ofa frame-support having a supporting surface extending rearwardly anddownwardly, a portion of said supporting-surface being formed on asection pivotally at tached to the main part.
